How to Choose the Right Size Custom Rash Guard

Key Takeaways

  • Take accurate body measurements: To ensure the right fit for your custom rash guard, measure your chest, waist, and hips accurately. Refer to the size chart provided by the manufacturer and measure yourself in form-fitting clothes or underwear for precise measurements.

  • Consider your body type: Different body types require different fits. If you have a lean and muscular body, choose a tight-fitting rash guard to accentuate your muscles. For a curvier body type, opt for a looser-fitting rash guard that offers more coverage.

  • Consider sleeve length and neck/collar style: The sleeve length of your rash guard should be chosen based on the season and your comfort. Short sleeves provide breathability in summer, while long sleeves offer more warmth in colder months. The neck and collar style should also be selected based on your preference for a looser or tighter fit around the neck.

If you’re planning to hit the water and engage in some water sports activities, one of the essential things you need is a custom rash guard. A rash guard not only protects your skin from the harmful UV rays but also offers comfort and flexibility during water activities. However, choosing the right size custom rash guard can be tricky, and a poorly fitting one can ruin your experience. In this article, we’ll provide you with a comprehensive guide to help you choose the right size custom rash guard.


Before choosing a custom rash guard, it’s essential to understand its purpose. A rash guard is a type of athletic shirt designed for water sports activities. It offers protection against harmful UV rays,  and other waterborne irritants. Additionally, it provides comfort and flexibility during water activities.

 Take Accurate Body Measurements

To find the right size custom rash guard, you need to take accurate body measurements. Measure your chest, waist, and hips, and refer to the size chart provided by the manufacturer. Ensure that you measure yourself in your underwear or form-fitting clothes to get accurate measurements.

 Consider Your Body Type

Everyone’s body type is different, and it’s crucial to consider this when choosing a custom rash guard. If you have a lean and muscular body type, you may want to choose a rash guard that is tight-fitting to accentuate your muscles. On the other hand, if you have a curvier body type, you may want to choose a rash guard that is looser fitting to offer more coverage.

Consider the Sleeve Length

Custom rash guards come in different sleeve lengths, and it’s essential to choose one that suits your needs. If you’re engaging in water sports activities during the summer, a short-sleeved rash guard will offer more breathability and comfort. However, if you’re engaging in water sports activities during the colder months, a long-sleeved rash guard will offer more warmth and protection.

 Check the Neck and Collar

The neck and collar of a custom rash guard are also important factors to consider when choosing the right size. If you prefer a looser fit around the neck, you may want to choose a rash guard with a crew neck. However, if you prefer a tighter fit around the neck, you may want to choose a rash guard with a mock neck or a high collar.

Determine the Level of Compression

Custom rash guards come in different levels of compression, and it’s essential to choose one that matches your activity level. If you’re engaging in low-impact activities such as swimming or surfing, a rash guard with a low level of compression will suffice. However, if you’re engaging in high-impact activities such as water polo or wakeboarding, a rash guard with a higher level of compression will offer more support.


Choose the Right Material

The material of a custom rash guard is another critical factor to consider when choosing the right size. Rash guards are made from a variety of materials such as polyester, spandex, and nylon. Polyester is durable, quick-drying, and offers UV protection, making it an excellent choice for water sports activities. Spandex is stretchy, lightweight, and offers flexibility, making it an excellent choice for water sports activities. Nylon is lightweight, breathable, and offers quick-drying properties, making it an excellent choice for water sports activities.


 Try It On

Once you’ve determined your size and considered all the factors mentioned above, it’s essential to try on the custom rash guard to ensure a perfect fit. When trying on the rash guard, make sure it’s snug but not too tight, and it allows for comfortable movement. Check that the sleeves and body length are at the right length and don’t restrict movement. Move your arms around and simulate the motions of the activity you’ll be doing to ensure that the rash guard provides enough flexibility.
